Having them doesn’t guarantee anything. I’ll list some teams with Elite freshmen off the top of my head:
2025 Duke - Final 4
Zion Duke - Elite 8
2017 UK - Elite 8
2015 UK - Final 4
2015 Duke - Title

2012 UK - Title
2011 UK - Final Four
2010 UK - Elite 8
All deep runs. Talent can take you a long way. If you knock on the door long enough you’ll break through.
You can look at UConn, Villanova Kansas and UNC as teams that have won recently without elite freshmen, so there’s multiple ways.
Personally I like Houston’s makeup. They’ve got two really good freshmen along with a core group.
